On a traditional dual magneto system, both magnetos are timed to fire at 25 degrees before Top Dead Center (TDC). When starting the engine, the ignition switch grounds the ‘P’ lead to the right magneto, stopping it from firing. Meanwhile, the left magneto with the impulse coupling can still fire.
Electroair has developed a 4-cylinder ignition system for certified aircraft. This system is a very active project with the FAA and is making progress toward ts STC for Lycoming 4cyl engines . This system was developed using lectroair’s previous system generations - incorporating all of the latest product improvements.
